Definitions

  • the invention relates to a control device, in particular for the control of machines, with a control element mounted in a housing and movable relative to it.
  • Such devices are used today in different areas of technology, such as machines, aircraft, remote controls, wheelchairs or computers. There are basically two ways of detecting the deflection of the moving control element.
  • a deflection of the control element can first be transferred mechanically to another component, by means of which the deflection is electrically detected. This information is then used to control the corresponding machine etc. It proves to be a disadvantage that the detection of the deflection is only imprecise due to the mechanical transmission, the high sensitivity to dirt and the signs of wear.
  • control element can also be designed such that at least part of the deflection detection required detection device is integrated in the control element, so that a "direct" detection of the deflection is possible.
  • This integrated part can be, for example, a magnet that is deflected between fixedly mounted coils. The magnetic field changed by the deflected position of the magnet is detected by the coils and used as a control signal. Since the changes in the inductance due to the shifted magnetic field are not linearly proportional to the deflection of the control element and thus do not permit precise analog control, the analog signal must be converted into a digital signal via filter and conversion electronics.
  • part of the control element can be the movable part of a valve, so that a "direct" influence on a hydraulic or pneumatic control can be exerted by deflecting the control element.
  • the disadvantage here is that, on the one hand, the control cannot be carried out with the desired precision and, on the other hand, the distance between the control device and the component to be controlled must be bridged by means of hoses.
  • the object of the invention is to provide a control device which enables a direct detection of the deflection of the control element without a mechanical transmission of the deflection to a detecting component and which ensures high detection accuracy, the control device being insensitive to dirt and free of wear.
  • This object is achieved in that the relative movement between the housing and the control element is detected by at least one combination of at least one transmitting and receiving unit on the one hand and a surface corresponding to it on the other hand, the corresponding surface has reflecting and non or less reflective sections and the transmitting and receiving unit on the one hand and the corresponding surface on the other hand are alternately provided either in the housing or the control element.
  • Mutual in the sense of the invention is understood to mean that one of the two elements (transmitting and receiving unit on the one hand or corresponding surface on the other) is provided in the housing and the other element on the control element.
  • the transmitting and receiving unit emits light signals which - if they hit a reflecting section of the corresponding surface - are reflected. If the control element is set in motion, the emitted light signals alternately hit reflecting and non-reflecting or less reflecting sections and are accordingly only reflected back by the reflecting sections. The changes between the reflected light signals and the pauses, where the light signal strikes a non-reflecting or less reflecting section and is therefore not reflected, are detected by the transmitting and receiving unit. The pulses thus obtained can then be used to control the machines.
  • the transmitting and receiving units can each be arranged twice for one direction of movement. These can be compared with each other using electronics. If the values differ, e.g. B. be interpolated or an error message is issued.
  • the arrangement of the reflecting and non-reflecting or less reflecting sections on the corresponding surface can correspond to the later area of application be formed (e.g. dimensions of the individual sections, linear, logarithmic or other arrangement of the sections, etc.).
  • the corresponding surface (s) can expediently be provided on a movable control stick serving as a control element, and the transmitting and receiving unit (s) can be attached to the stationary housing. In this case, either the corresponding surface can be moved between the transmitting and receiving unit or else around the inside of the transmitting and receiving unit.
  • An advantage of the embodiment in which the corresponding surface encloses the transmitting and receiving unit from the outside is simple shielding of the transmitting and receiving unit against environmental influences and thus also against contamination.
  • Such a design of the control device permits use as a joystick, for example in machines or aircraft.
  • the joystick can be deflected in different directions, as a result of which the position of the reflecting and non-reflecting or less reflecting sections of the corresponding surface are changed and run along the stationary transmitting and receiving unit.
  • the transmitting and receiving unit (s) can be attached to a movable control stick serving as a control element and the corresponding surface (s) can be provided on the stationary housing.
  • the control element is a sphere or a hollow sphere half, which acts as a corresponding deflectable surface of the transmitting and receiving unit (s) fixedly attached to the housing. faces.
  • the control stick can even be rotatably mounted without twisting the control stick having an influence on the detected deflection. Furthermore, a production-intensive anti-rotation lock is no longer necessary and there is no need to align the control stick during assembly.
  • control stick can have a device for independently actuating a third transmitting and receiving unit or a corresponding surface, which in turn cooperates with a stationary corresponding surface or a stationary transmitting and receiving unit.
  • a further function can be controlled by rotating an element located in the control stick, at the lower end of which a third transmitting and receiving unit or a corresponding surface is provided.
  • the surface area relevant for this control function can also be located on the outer surface of the sphere or on the inner surface of the hollow half of the sphere and can consist, analogously to the aforementioned surfaces, of reflecting and non or less reflecting sections.
  • control element 1 shows a control device consisting of a control element 1 and a control stick 2 attached to it.
  • the control element 1 is designed as a ball which is open at the bottom and is movably mounted in a housing 3.
  • the housing 3 On the inside, the housing 3 has a stationary stand 4, on each of which two opposite transmitting and receiving units 5 and, for this purpose, shifted by 90 °, two opposite transmitting and receiving units 6 are mounted.
  • control element 1 has a plurality of surfaces 7, 8 corresponding to the control and reception units 5, 6.
  • corresponding surfaces 7 and 8 are not divided individually, but are designed, for example, as a circumferential spherical section.
  • a further transmitting and receiving unit 10 is provided on the rod 9, which cooperates with a further corresponding surface 11 on the inside of the control element 1.
  • the control stick 2 which can be rotated in the housing 3 from below, as a result of which the corresponding surface 11 of the transmitting and receiving unit 10 is better illustrated.
  • the transmitting and receiving unit 10 is also rotated so that the reflecting and non-reflecting or less reflecting sections of the corresponding surface 11 are scanned and counted.
  • the control element 1 itself is not rotated.
